So a common thing to do on live with bow right now is light/heavy attack → instant penetrating shot, but now there seems to be a 1 second cooldown between attacks that makes this impossible? Seems like a massive nerf and makes the bow feel bad to use.
Musket reload speed also seems to have been significantly decreased - which is good because its a buff, but bad because its a bad buff. All this serves to do is let musket users easily murder anyone in light armor without addressing the main issue with it, which is that it sucks against heavy armor users. A better change would be to add armor pen.
As a side note ice gauntlet heavy attacks seem to have been slowed down quite a bit as well.
